so that the latter need only be loaded. periodically instead ofcontinuously, as is common practice, and which method is of advantage insaving the crop as the machine and vehicle are subjected to rough travelthrough corn fields and material loss of shelled corn occurs when thevehicle is continuously loaded during the irregular movements of boththe` vehicle and the machine. 'I'he movement of the cobs and trashthrough the outlet 44 is retarded by a damper 46 which may be manuallyadjusted to control the ilow of the material so that a mass thereof maybe retained to be thoroughly treated'by the cylinder 22 and'dischargedthrough the outlet as desired. As the cobs and heavy trash are propelledthrough the outlet, and the nner trash and kernels forced between thespaced bars 21 and onto the screen 31, the blast from fan 40 discharginglongitudinally through the screen sustains the debris thereabove andpermits the kernels to pass through the screen to be directed to theauger 34 and thereby delivered to the chute 37 for nal discharge, whilethe cobs and trash are stepped to the opposite end of the screen by theshaking action thereof and disv charged through the outlet 47 onto theground or otherwise disposed of.

I claim as my invention:

1. In a corn picker-Sheller, means for gathering and picking ears fromstalks, means for removing ears and trash from the gathering and pickingmeans, a receptacle communicating with the removing means for receivingmaterial discharging therefrom, means in the receptacle for shellingcorn from the ears thereof, means in the receptacle beneath` theshelling means for separating shelled corn from trash and cobs, andmeans associated with the receptacle for conveying shelled corntherefrom and discharging the same to another receptacle.

2. In a corn picker-Sheller, means for gathering and picking ears fromstalks, means for removing ears and trash from the gathering and pickingmeans, a receptacle beneath and communicating with the removing meansfor receiving material discharging therefrom, means in the receptaclefor shelling corn from the ears, a shaking shoe in the receptacle havinga screen upon which shelled corn and trash from the shelling means aredeposited, means associated with the shoe for winnowing shelled cornfromtrash whereby the corn passes through the screen and into the shoe,and means associated with the shoe for conveying shelled corn therefromand discharging the same.

3.
